An educational illustration showing several DNA strands with a focus on the different types of mutations: a frameshift mutation through deletion and a deletion with a substitution mutation. Also, visualize a fact box stating that the mutation causing cystic fibrosis is a deletion. Depict chromosomes, emphasizing that they contain DNA. Lastly, hint towards an epigenetic change as an oversight, altering an organism’s expressions without changing the DNA sequence.

1.A DNA segment has base order AGC TTA TCG. Which copy exhibits a frameshift mutation through deletion?

D. AGA TTT CG
2.A DNA segment has base order CCC ATA GCT. Which copy exhibits a deletion in the first codon triplet and then a substitution mutation?
D.CCA TAA CT
3.Which type of mutation causes cystic fibrosis?
D. deletion
4.Which statement about chromosomes is true?
C.Chromosomes contain DNA
5.Which modification affects an organism’s expressed characteristics while leaving its DNA sequence unchanged?
B.Epigenetic change

I just wanted to let y'all know, you guys are the only reason I'm passing biology. love you guys <3

100%! Though, the answer to number one is "AGC TTT CG" not "AGA TTT CG".

Mr. is right I got 100%

Thanks Man!

Thanks. This is 100% correct

Thank you Mr.! 100% For number one it's AGC TTT CG not AGA TTT CG. But still got it correct. Thank you!

they changed it now for question 5

If a cell has two copies of each chromosome, which type of cell is it?

answer is: A diploid cell

all correct for HONORS BIO!!! some of yall complaining that its incorrect but are probably in standard bio

Still valid as of 1/5/22

Mr. Is 100% correct for Honors Biology Genetic Variation From Errors! Thx dude!

Mr. still valid
